Application filed February 29,1924. semi Nb. 696,066.

This inventionrelates to means for and method of' handling chips, which are formed envelope blanks.

An object of the invention is to provide a chip removing device comprisingachip engaging element .which when actuated moves in an orbit to one side of its. support and in a plane extending transversely of the material acted upon to remove the chips.

Another object of the invention is todeposit the removed chips on a conveying device by which they are carried to a suitable container-jinto which they are discharged. Another object of the invention is to accumulate the chips on the conveying device so that they may be discharged therefrom in packs to .prevent'their being blown about and becoming entangled in the machinery.

A feature of the invention relates to means to fold the chips so that they may be so accumulated or stacked by placing them one Within the other,,i. e., nesting them, on the conveying device, the speed of the conveying device being slow as compared with the movement of thechip engaging element to thus assist in accumulatingthe chips.

Another feature of the invention relates to means to adjust the throw of the chip engaging element to thus vary its extent of overlap from the edge of the material for chips of different depths. I

Still another feature of the invention relates to adjustable means to vary the movement of the chip engaging element towards the conveying device.

A further feature relates to means to vary the length of the chip -engaging element according to the location. of the material.

The above and certain other objects of the invention will now be described with particular reference to a preferred form of em- 7 bodilnent ofthe invention llustrated. 1n the accompanying drawings, in which:

OF, NEW YoaK, N. Y,, A CORPOBA- Figure 7 is a detail sectional view showing the connection between the chip engaging element and its actuating means.

In the presentapplication of our invention a continuous web 10, Figures 3 and 4, of envelope blanks 11, having chips 12 in its edges, is advanced by feed rollers. 13 and 14, Figure 5, over a table15, secured to a main frame 16. In removing the chips from the web there is utilized a device which comprises a chip engaging element having a blade 17, normally disposed above the web lOas in Figure 1. Said blade is actuableas hereinafter described, and is sotimed with reference to the feed of the web that it is depressed every time a chip is brought into tates in the mainframe 11, it being driven in any suitable manner. Saidshaft has secured thereto a bevel gear 20, meshing with a bevel gear 21, to rotate the latter in a clockwise direction, Figure 1. The bevel gear 21 rotates on a stub shaft 22, secured to a bracket 23 of the main frame 10, Figure hub 31, and securedto the side of the gear 26 by a screw .32 which extends thru a slot 33 in an extension 34 on said huband' on the side opposite to the crank arm 30, the screw 32-being threaded into the gear'26. Thusit will be understood that when. the gear 26 is rotated the" crank arm rotates with it.

The chip engaging blade 17=is-provided with a stem whichis slidingly supported in a bearing block 36 talc-ruined on a pin 3. or disc 38 secured by a nut to a bracket 39 on the main frame 16, the nut 40 being threaded on a binding post ll, Figure 2, extending from the opposite side of the disc 38 and extending thru the bracket 39. The stem 35 of the blade is connected near its end to the crank arm by a coupling 4-2. The blade stem 35 extends thru a hole in a block ll of said coupling 42. To fasten the stem to the coupling block there is provided a bolt in a hole 46 and extending at right anglesto the stem The bolt 45 has a segmental groove or kert' t? thru which the stem 35 passes so as to be partially embraced by said bolt, the latter being provided with a nut l8 at one end, which when drawn up binds the bolt 45 against the stem 35 to securely hold the latter in place on the coupling block 4 1-.

The coupling block 44: is supported by means of a wrist pin l9 secured to the crank arm 30, the wrist pin having for this purpose a rectangular head 50 received in a slot 51. The head 50 is provided at one end with a circular flange 52 to bear against one side of the crank arm 30, the other end of said head having a binding post 53 with a nut threaded thereon to bear against the other side of thecrank arm to tighten up and to bind the wrist pin in place. The wrist pin 49 has anut 55 at its end to keep the coupling block 4 1 on said pin.

From the foregoing it will be understood that as the gear 26 rotates it causes the wrist pin 49, which is the eilective pointof connection with the blade stem of the chip engag ing element to travel in a circle, thus vibrating the chip engaging element (which in effect is a. lever moved about the stud or fulcrum 37) and also moving said element hack and forth in the bearing block or sleeve 36. This combined vibratory and reciprocatory movement of the chip engagingelement causes its blade 17 to travel in an orbit eomorising four stages, substantially as indicated at A, B, C, D, Figure 1. During the first stage of its movement the blade moves from A to B crosswise of the material or web 10 to remove the chip by drawing it thru the slot 18, in the table. This movement is the working stroke and is performed at relatively fast speed because the leverage of the chip removing element between the fulcrum 37 and the point of connection 49 is' comparatively short. During the second stage of its movement, namely -1"rom B to C, the blade moves beneath the web and outward beyond the edge preliminary to moving past the edge from C to D, which is the third stage of the movement. The blade then moves inwardly over the material from D to A, this being the fourth stage of its movement. thus completing one cycle of operation. The working stroke of on shafts (iG and 67 respectively.

the blade is completed slightly beyond the point B from which the return stroke of the blade and also its withdrawal from the removed chip, begins. 7 It will be understood that the blade move substantially parallel to the web from B to C and from D to A.

In addition to the chip removing device arranged at the left-hand edge of the web 10 there is another one arranged at the right-hand edge as shown in Figure l.

These two devices are o iositely dis-nosed.

and driven in opposite directions and they are so timed with respect to each other and with respect to the web to move downward ly together every time a pair of chips is brought into their paths.

It will'be understood that webs oi various widths may be employed in the device ol' the present invention. For this purpose each chip removing element is adjustable in the direction of its length and with reference to the location of the edge ot web. To this end the length of each chip engaging ele ment may be varied to cause it to extend inwardly over the web more or less as de sired. To vary the length of said element the nut 48 is loosened, thus relieving the clamping effect of the bolt .on the stem of the chip engaging element, after which the latter may be shifted back or forth in the coupling block 44; according to the desired length. 'After adjusting said element it may again be clamped in place on the ceupling'block by drawing up on the nut l3.

it will further be understood that the depths of the chips, or in other words, the distance that they extend inwardly from the edge of the web, may vary acc irding to the six and character of the envelope blanlts. To permit the device to be used for chips of various depths, the coupling block ll is adjustable on the crank arm to increase or decrease the lhrow of said chip removing element.

The adjustment of the point of CGlilKiiF tion is effected by loosening the nut 5. so that the wrist pin may be moved toward or away from shaft 27 according to the exten of throw desired. After adjustment, the wrist pin is fixed in place by the nut It will be understood that as the Gear 96 rotates the wrist pin 1-9 revolves freely within the .coup lin block ll, said'block remaining always at right angles to the stem 35 of the .chip removing element.

Means comprising a conveying device 56 are provided to receive the chips from the blade 17 and carry them to a container 51' into which they are discharged. The conveying device includes two belts 5S and 59, the belt 58 running over rollers or pulleys 60 and 61 onsliatts '62 and 63, respectively, and the belt 59 running over pulleys G l and The loo 'fii) conveyer belts are so placed as to have two oi their strands face to face and closeto each other to form what may be termed a guideway, 68, extending downwardly from the rollers 60 and 64 to the container 57.

The blade 17 moves between the rollers 60 and 6.6 to. deposit the chips on the belts 58 and 5.9 by which they are drawn downwardly and guided to the Container.

"The conveyer belts may be driven in any suitable manner, and preferably "at a comparatively slow speed with respect to the vibr tions of the chip blade 17 so that the chips are stacked'or accumulated between the conveyer belts 58. v

It will be observed that each chip is folded as it is passed. thru the slot 1.8 of the table and is nested within the reeedingly removed chip. The chips are ed out between the-pulleys 61 and 62 in a sort ofstrip which,

when it gets heavy enough, breaks to thus discharge the chips in packs into the container 57. Flying about of individual chipsv is thus prevented.

The rollers and 6 1 are separated sufficiently to allow theblade 17 to move clownwardly between them to depositthe chips on the belts 58 and 59. The rollers 61; and are placedclose enough to cause the belts to bear 'firmly against each other and thus produce a sharper-ease in each chip. v

The belts 58 I and 59' of the conveying device extend under the table 15 to the chip ren'ioving device at the other edge of. the

web 10, so that a single pair of belts. may be effective to convey the chips removed by both devices. Y i

Means are also provided for each chip removing element to adjust its movement toward the rollers 60v and (i=1 ot'the conveying device. to enable it to move sufficiently down between the rollers to properly deposit the chips thereon. Another reason forthis adjustment is to cauie chips of various widths to be completely drawn thru the table 15 to avoid cloggingotthe slot 18, it being necessary for the blade 17 to move down further for wide chips than for narrow chips.

To adyust the movement oi the blade 17 towards the conveying device, the fulcrum pin 37 on whiehthe sleeve 36 is inounted' is ecrcntrically mounted onthe disc 38, Fig that after the nut it) has been urea? 1 and "J, loo-cued the due may be rotated about the c axis of the binding postal to raise or lower. l

the t'nlcruinpin 37 and consequently raise or lower the bladel'? by means of the sleeve 36 in which the stem 35 guided, the chip engaging element being swung during such adjustment about the wrist pin 49.

he sleeve is held on the fulcrum pin 37 by a nut 70, and said fulcrum'p'in is short enough so as not to interferewith the movc ment of the stem 35 of the blade1-7.

It will be understood that although the inv'ention is illustrated in connection with en-" velope blauksand these in a continuous web, it maybe used in connection withblanlis oi ,otherikin'ds ot' containersjand that the blanks maybe separated instead of connected in a continuous web.
